BIODIESEL PRODUCTION SYSTEM BASED ON RAPESEED OIL FOR AUTOMOTIVE ENGINES Russian patent published in 2023 - IPC C11C3/04 C10L1/00 C10L1/14 C10G73/04 

FIELD: agricultural production.

SUBSTANCE: used in the production of biofuel from rapeseeds with its subsequent use in automotive engines, for example, for tractors of the MTZ-80, MTZ-82, etc. brands. A method for the production of biodiesel fuel based on rapeseed oil for automotive diesel engines is described, including separating the deposited sediment in rapeseed oil, mixing purified rapeseed oil with diesel fuel, using clarification to separate rapeseed oil from the sediment, followed by fine purification of rapeseed oil by filtration with the addition of diesel fuel in a ratio of 2:1, cavitation dispersion lasting 30-40 minutes at a temperature of 70°C and control the quality of mixing, and pre-heat the rapeseed oil to a temperature of 70…110°C, and after its fine purification, the quality is analyzed for the presence of finely dispersed impurities in it and supplied in doses for mixing with diesel fuel.

EFFECT: improved quality of biodiesel fuel.
